on my system, I see:

CMakeCache.txt:TCL_INCLUDE_PATH:PATH=/usr/include
CMakeCache.txt:TCL_LIBRARY:FILEPATH=/usr/lib/libtcl.dll.a
CMakeCache.txt:TCL_TCLSH:FILEPATH=/bin/tclsh
CMakeCache.txt://Details about finding TCL
CMakeCache.txt:FIND_PACKAGE_MESSAGE_DETAILS_TCL:INTERNAL=[/usr/lib/libtcl.dll.a][/usr/include][v()]
CMakeCache.txt://Details about finding TCLTK
CMakeCache.txt:FIND_PACKAGE_MESSAGE_DETAILS_TCLTK:INTERNAL=[/usr/lib/libtcl.dll.a][/usr/include][/usr/lib/libtk.dll.a][/usr/include][v()]

Just to be sure, are you  referring to plplot-5.9.9
